According to the LVM howto, there is a patch you can apply to the Kernel to
grow (not shrink) the size of a mounted ext3 fs, but I would not use it in
production systems unless it's stable.

I learned about the fix for ext3 but when you are talking large
production systems in the terrabytes, unstable will not cut it.
I appreciate the response about SGI's Irix port. I thought it was the
same as aix. but back to the original question, how stable and how
good a performer is XFS?
Just last week I had a hit (dasd over-run) where the Linux system
didn't know what to do with the H/W error. So the LVM/XFS will most
likely go to min-disk under zVM. No more DEDICATED devices in this
shop.
